Do you have a link to a data set verifying this claim? (Btw, I do know that it's true I just want a link to a data set that Google may not link to.)

Washington Post Co. Sells Newspaper and Keeps Kaplan Kaplan Inc., now makes up a larger portion of the Washington Post Company, which Monday announced the sale of The Washington Post for $250 million to Jeff Bezos, the founder and CEO of Amazon.com.

2/

This was why it was profitable. When Bezos bought it, it had an operating loss of about $40 mil. It now has one of $100 mil. That is, nothing has changed -- except that Bezos didn't buy the profitable part of the company:

1/ (Haven't read the article.) A reminder: the Washington Post was sold to Bezos without Kaplan Higher Ed. That is, the latter made up half of the revenue and ALL of the profits of the Post, before Bezos. In other words, the Washington Post used to be a test prep company w/a newspaper.

Traffic collisions in India - Wikipedia

You should have included the data from India! What's (very) surprising is that, using data from '23, it has 12.5 road injuries per 100k people. In other words, it's only slightly higher than the US!

If you've ever driven in India, this statistic should shock you.

Error function - Wikipedia

1/ I just discovered this -- and can't believe I just did. There is no solution to the following: find the integral from infinity to minus infinity of e^((-z^2)/2)dz, where z is any real number.

Specifically, it's been proven that there's no solution to this indefinite integral.

How Wingtech became the latest cautionary tale in the US-China tech war Some analysts link seizure of subsidiary by Dutch authorities to new rule issued by the US Bureau of Industry and Security.

2/That is, this could motivate the CCP to retaliate against the US by restricting rare earth imports.

In any case, this news story is not getting headlines in the US but it has the potential to greatly influence the trade war between the US and China.

1/Nexperia is a 100% Chinese-owned company based in the Netherlands. It makes semiconductors primarily for cars. Last week, the Dutch gov't nationalized it. That is, they formally took over ownership of the company. Why? It seems to be because of US pressure.

This has the potential to blowup.

HEARTLESS LOVE: CHRISTIAN NATIONALISM IN APARTHEID SOUTH AFRICA AND TRUMP’S AMERICA β€” Earth and Altar Many Americans refer to β€œChristian nationalism” as a new threat, but the concept has deep and unsavory roots in South African history.

South Africa's apartheid system was designed according to Christian teachings and Christian nationalism -- and Afrikaner nationalism. My point: Christianity has been -- and likely will be -- a force against its core values:

Worth considering: tariff revenue is log-linear -- not linear. That is, as tariff revenue increases, Americans will change their behavior to avoid them and therefore they'll decrease. Or, the longer the tariffs are in place, the revenue generated logarithmically decreases.

Immigration: -3.4%

This averages to -16.7%. Obviously, a weighted average can be used to get -7.5%. The question is...

What's the point of publishing a poll, such as this, which most likely can be statistically classified as an outlier? I mean, I assume that this poll cost many thousands of dollars to do. Why spend the money when 1) the result is predictable 2) all your others polls are also outliers.
